Be it known that I, GUS F. Liann, a citi-I.;

Closures tor Incinerators, ot which the vtollowing is a specii'ication.`

This invention relates improvements in charging hole closures `for incinerators.

1t is customary in charging or deliveringA garbage and trash to incinerating furnaces to drive the vehicleover a hole inthe top oit' thecon'ibustion chamberfand dunip the load through the hole into said chamber. The.V hre directly under this hole becomes inf tensely hot and when'the hole is not being used, it must be closed. Owing to the' in tense heatV under the hole, particularlywhen closed, metal covers which are exposed *di-I rectly to the flames or the het gases soon' warp and brealn Further such a cover becomestoo hot to handle satisfactorily.

The object of my invention is to provide a charging hole closure wherein no metal is Xposed tothe fianies or the direct action of the hot gases` and whereby the charging hole is protected against the same.`

A further object is to provide a metal covertor the upper end ot the hole which may be handled inthe usual manner and a protecting or secondary cover or tile or' tire resisting` material suspended'therefrom at the bottom of the hole` and substantially closing the saine, whereby the lining of the hole and the metal cover are kept comparatively cool. f

Another object of the invention is to provide a charging hole closure formed or' a tile of fire resisting material and a metal suspending or supporting member therefor fully protected from the ire by said tile.

A construction designed to carry'out theV invention will be hereinafter described to gether with other features ofthe invention.

kThe invention will be more readily understood from a reading of the following vspecilication and by reference to the accompanying drawings, in which an example et the invention is shown, and wherein:

Fig. 1 is a sectional view of one of the charging holes of an incinerator equi pcd with a closure constructed in accor ance with my invention,

to new anduse'tul f Fig. 2 is a plan view of the lower cover or closure member, v

Fig. 3 is a cross-sectional view on the line 3-8 of 2, i

Fig. Ll is a cross-sectional view on the line 4 4 ot Fig. 2, and

Fig. 5 is a cross-sectional view on the line .5-5 @erige In the drawings the numeral 10 designates the arch or' the combustion chamber of anfincinerator or any other furnace with which the invention may be used. The furnace roof lliis' above the arch and afloor 12 is laid upon the roof;` A downwardly converging circular opening. 13 is formed in the floor and roof and is continuedA An upwardly flared annular metal lining or hopper 15 is fitted in the opening and has n'iEN'rA OFFICE.vv

an outwardly directed iiange 16 at its upper n end counter-sunlrin the floor 12.

, A circular fiat metal plate or cover 17 rests upon the flange flush with the door. An eye bolt 18 is fastened inthe cover by nuts 2O fand affords a point of connection with means used to lift and place the closure. A pair ot n spaced bolts 19 hang through the cover, being fastened by nuts 21 engaging the under and upper sides of said cover.

The bolts 19 have eyes 22 at their lower ends which engage in the eyes of bolts 23 passing through an annularmetalhanger 24. The

hanger is made of two semi-circular sections and has .depending side walls 25 and their lower ends areprovided with inwardly directed semi-circular flanges 26. vA circular tile 27 oi' re proof clay or other iire resisting material is mounted in the hanger and has a diameter larger than that of the hanger so as to project beyond the sainer and shield it from the iire below. The 'diameter of the tile is such as to cause the latter to substantially close the lower end of the hopper, sufficient clearance being allowed to move the tile vertically. Owing to the upward flare of the hopper the ytileV requires but little-clearance at the bottom of the hopper. The tile,as described, projects circuinterentially beyond the side walls 25 or" the hanger.

An enlarged annular boss 29is formed on well au sfide recesses 3l for the bolts 32 ot splice. platee` 33 which unite the sections et the hanger. rlhe tile is of course east in one piece. The hanger sections are placed around the boss 2S) with the walls 2,5 einbraeing the sides o't' the boss and the iangee 26 seated in the grooves Q8. It' the tile is cracked or broken it can he 'eadily replaced. t w`ll he seen that. the underside ot' the tile 2T is presented to the lire and the hanger is protected theretroin hy the tile. The greater portion of the hopper is Shut oli' from the fire and the nietal Cover l? above is lar enough reinoved to ren'iain eoinparativelv Cool. lfhen it is 'desired to open the hole, suitable hoistingrnieans (not shown) is ronneeted with the liolt- 18 and the closure ele vated until the tile or lower cover is ahove the vehicle Carryingv the load to he dumped through the hole. After the charge is eeniplete the Closure is lowered until the cover 1T is in place, the tile being' guided into the hopper l5.

lt is: apparent that inanyv methods o'i supporting the tile and suapending' it iroin the cover may be Carried out as well as changes in the tile hanger, all such as come within the scope olf appended elaiins are included. lt is intended herein to Cover the use of the tile and hanger alone, irrespective of how .they may be mounted in the hole.

that I claim, is: l. ln a Charging hole Closure tor urnaees.

an annular fire resisting n on its upper side and a eireunit'ei'ential groove, an annular split metal hang'e eurrounding the boss and having,` an inwardly direeted {lang-e engaging in the groove ot the tile, splice plates connecting' the parts olf the hanger, the tile extending' radially beyond the hanger and plates and lneans 'l'or supporting the hanger in a charging' hole.

Q. ln a charging` hole Closure l'or lurnaees, the combination with a inetal hopper, ot a nietal cover resting' upon the upper end ol the hopper, supporting' elenients suspended from the cover in the hopper, av niet-al hanger attached to the lower ends o'tA the supporting',v elements, and a tile of lire resisting' inaterial suspended frein the hanger within the lower end ot the hopper, the cover and tile heinev removable upwardlj as a unit to provide an unobstructed passage through the hopper.

il. ln a. rharging hole closure for iui'iiaees, a cover plate, an eye on the plate, 1oolts depending 'trein the plate, a split hanger having' a retaining' flange, means for suspending' the hanger at the lower ends ot' the bolts, and tile of fire resisting' material surrounded hy the hanger and receiving' the retaining flange.

In testimonyv whereotl I affix my signature.
